Having had a chance to look at it more the plumage falls within range of variation for dark-morph juvenile Red-tailed and not Rough-legged, particularly in lacking a dark tail tip, having uniform underparts, and the dark face/hood as others have pointed out. I had not gone beyond the first two clips when looking quickly last night, which give it more of a RLHA look; e.g., the small-looking head and bill when looking away from the camera. But it looks much more like a RTHA in shape during later clips with the raven, etc.
